Will Robin Thicke Woo Paula Patton Back with New Song at the Billboard Music Awards?

It looks like Robin Thicke, 37, is still trying to woo Paula Patton back if the title of his new song is any indication. The singer is set to perform at the Billboard Music Awards on Sunday and according to a source he will sing his new track "Get Her Back."

Thicke, who separated from Patton in February, hasn't commented on the track yet, but he told PEOPLE recently that he plans to reveal "everything" in an upcoming album.

"What everybody's wondering about, they're going to hear it all in the album," he said. "Everything about this moment in my life – this amazing year I just had and what I'm going through personally has actually ignited some of the best writing I've done in a long time."

Thicke joins a long list of performers – including Miley Cyrus and Jennifer Lopez, who will also receive the icon award – at this year's show. The Billboard Music Awards will air live on ABC at 8 p.m. ET.
